FTP no longer works on my mac

My macbook pro is no longer able to ftp. I know its my computer because when I ftp from my iPhone there is no issue. I have tried multiple ftp servers, replaced the router / modem that my isp gave me, and done a factory reset on the modem.

The only recent update I have done was installing norton antivirus. However, when I turn the firewall completely off it still doesn't work. I have checked with my isp and hosting company and there is no blockage on my ip. This issue has been consistent for 3 days.

Short of a complete reformat, is there a setting I can apply on my modem (hitron from rogers cable), or a setting on my mac I can change?
